ATONIIZER.

SPECIFICATION forming part of Letters Patent No, 451,643, dated May 5, 1891.

Application filed March l2, 1891. Serial No. 384,809. (No model.)l

To all whom t may concern:

Be it known that I, JOSEF SCHOETTL, a resident of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Nasal Atomizers, ot' which the following is a full and clear description.

My invention consists in constructing a nasal atomizer in the improved manner hereto inafter clearly shown and described.

The object of this invention is to so construct an atomizer that the inner f1uid-sup ply tube and the outer air-supply tubeshall each be a continuous tube, still allowing the air to pass between them and providing for a proper support of the inner tube in the outer.

My invention is illustrated by the accompanying drawings, in whichof an automizer of my construction, showing the bulb-connection an d the liquid-containin g bottle. Fig. 2isa longitudinal sectional view ot the atomizer proper. Fig. 3 is a cross-section on the line 3 3, Fig. 2; and Fig. 4 is a detail view of the threaded section of the inner tube, showin the air-passage in the screw enlargement.

A is the exterior tube, having a suitable 3o nozzle a at one end, the other` end being formed to lit into the neck of a bottle I. The pipe A has a branch B, to which a'pipe D is to be coupled, by which airis iorced into both the bottle and thenozzle a.

Vithin the exterior pipe A is an inner pipe E, which is provided with a threaded enlargement F, the enlarged threaded portion l) thereof being adapted to be screwed into a corresponding threaded portion cof the exterior 4o tube. This pipe E is sufliciently small to allow an air-passage between it and the exterior tube A. The threaded portion b ot the in- Figure 1 is a central longitudinal sectionner tube E ha-s one or more longitudinal grooves d to allow a passage ot air through this connection, or this groove may be cut inside of the outer tube at the threaded portion. The lower end of the tube E extends down into the liquid in the bottle, and the upper end extends up intothe nozzle a. lVhen air is admitted at B, part of the air goes down into the bottle and part goes up through the space between the two tubes toward the nozzle a, where it meets a jet of liquid forced by the air-pressure from the bottle I. -Vithin the nozzle the air and the liquid meet and a line spray is emitted from one or more suitable oritices in the. end of the nozzle.

Previously in nasal atomizers the tubes A E were made in sections, whereby the bore ot' the inner tube was reduced, rendering cleaning diiiicult. My tube E is a single piece, and my tube A,wi th its nozzle, is also a single piece. This renders them inexpensive, strong, and allows for the largest practicable bore. The threaded enlargement b, with its groove d, serves to support the tube E to form the space between it and A and to conduct the air in the grooves d. After the parts have been assembled, as in Fig. 2, the tubes can be bent, as in Fig. 1, whereupon they will b inseparable.

Having thus described my invention, I claim- The combination of the continuous outer tube A and its nozzle d and inner thread e with the continuous inner tube E, having the threaded enlargement 11 and the grooves (Z traversing the grooves ot' the threads, substantially as herein shown and doscribed.
